Database

Database is an organized collection of information.

In a relational database:

• Data is stored in tables.
• Each table comprises a number of columns of a particular data type such as Text, Number or Date.
• Information is stored in the rows of tables.
• Tables can be related to other tables using the concept of Primary Key and Foreign Key.

Whereas in Salesforce:

• It uses objects to store data.
• Each object comprises a number of fields which correspond to columns in a database.
• Data is stored in records of objects which corresponds to rows in a database.
• Objects can be related to other objects using relationship fields.
